We study different patterns of interference in WIMP-nuclei elastic scattering that can accommodate the DAMA and CoGeNT experiments via an isospin violating ratio fn/fp = -0.71. We study interference between the following pairs of mediators: Z and Z′, Z′ and Higgs, and two Higgs fields. We show under what conditions interference works. We also demonstrate that in the case of the two Higgs interference, an explanation of the DAMA/CoGeNT is consistent with electroweak baryogenesis scenarios based on two Higgs doublet models proposed in the past.

The Impact

Two Higgs doublet models with an additional pseudoscalar particle coupling to the Standard Model and to a new stable, neutral particle, provide an attractive and fairly minimal route to solving the problem of Dark Matter. They have been the subject of several searches at the LHC. We study the impact of existing LHC measurements on such models, first in the benchmark regions addressed by searches and then after relaxing some of their assumptions and broadening the parameter ranges considered. In each case we study how the new parameters change the potentially visible signatures at the LHC, and identify which of these signatures should already have had a significant impact on existing measurements. This allows us to set some first constraints on a number of so far unstudied scenarios.

Breaking Term

In two-Higgs-doublet models with exact [Formula: see text] symmetry, putting [Formula: see text] at the alignment limit, the following limits on the heavy scalar masses are obtained from the conditions of unitarity and stability of the scalar potential: [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text]. The constraints from [Formula: see text] and neutral meson mass differences, when superimposed on the unitarity constraints, put a tighter lower limit on [Formula: see text] depending on [Formula: see text]. It has also been shown that larger values of [Formula: see text] can be allowed by introducing soft breaking term in the potential at the expense of a correlation between [Formula: see text] and the soft breaking parameter.
